Most in-wall and in-ceiling speakers are 2-way (woofer-tweeter) designs. In-wall speakers are usually mounted well above eye level, for aesthetic reasons. Most people who choose in-walls don’t want to see speakers in their room, so they mount them high up on the wall, above the sight line. That’s great visually, but lousy acoustically. Ceiling mounted speakers are even worse: Invisible, but hardly an optimal acoustic situation! So to counteract the effects of bad placement, many wall- and ceiling-mounted speakers have tweeters that can pivot or swivel, so they can be “aimed” at the listening area. Not a bad idea, but not a perfect solution either. The problem is that the woofer in a conventional 2-way wall or ceiling speaker handles too much of the sound spectrum. The woofer in a normal 2-way speaker handles not only the bass, but it handles virtually all of the critical midrange and lower treble as well. And in the midrange/lower treble, woofers send out their sound like a flashlight
